Dates are flexible. This day-by-day plan is provisional until you choose exact travel dates.
From Gatwick Airport, follow signs to the railway station and take a direct Thameslink train towards London Bridge; the rail journey is usually around 30–35 minutes, but allow roughly 1½–2 hours door-to-door for baggage, finding the platform, delays, and check-in. A contactless card or Oyster normally works on this route, though check the fare at the station if using a non-UK card. From London Bridge station, St Christopher’s Inn London Bridge – The Village is a short walk; confirm the hostel’s check-in time and luggage-storage policy in advance, particularly if your flight arrives before the room is ready. After a long flight, keep the evening deliberately easy rather than adding another major attraction.
Walk from the hostel to Borough Market, where the covered halls and surrounding streets usually have a lively Christmas atmosphere, although individual stalls may close earlier than normal in the holiday period. Spend about 1½ hours browsing and have an informal dinner—allow approximately £12–25, more if choosing several small dishes. Good options vary by day, so look for something you would not usually eat at home rather than queueing for the most famous stand; keep a little cash as backup, even though cards are widely accepted. After eating, walk west along the South Bank from London Bridge towards Tate Modern, taking about an hour at an unhurried pace. This is especially atmospheric after dark, with views towards St Paul’s Cathedral, the river bridges, and the seasonal lights; wrap up warmly, as the riverside wind can be sharp.
Finish at The George Inn, tucked just off Borough High Street, for a relaxed drink or light supper. This timber-framed coaching inn is a good first-night stop because it feels distinctly old London without requiring a complicated journey back. Budget roughly £8–20 for a drink and light bite, and check the pub’s festive opening hours because Christmas schedules can change. From there, St Christopher’s Inn is only a few minutes away on foot, so you can return easily after settling in—an appealing option if jet lag catches up with you.
Start at Tower Bridge when it opens, allowing about 1½ hours for the high-level walkways, glass floors and Victorian engine rooms. Check the official festive timetable before setting out, as Christmas-period hours can change; adult admission is typically around £13–£15. From your hostel, walk north-east along Tooley Street and the river in roughly 15–20 minutes, or take the Tube to London Bridge and walk. The bridge is best early, before tour groups arrive, and the views towards the Tower of London are particularly good in winter light.
Continue on foot to the Tower of London, taking about 10 minutes via Tower Bridge Road and Tower Hill. Allow around three hours for the fortress, medieval interiors, ravens and Crown Jewels. Book an advance timed ticket—usually roughly £35–£40 for an adult—because Christmas-week availability can be limited; entry is not guaranteed without a valid slot. You will be outdoors for much of the visit, so wear waterproof shoes and warm layers, and arrive 15–20 minutes before the booked time for security and entry queues.
After the Tower, walk east for about 10 minutes to St Katharine Docks. Spend an unhurried hour circling the marina, looking at the boats and seasonal waterside displays, and warming up with a drink if needed. It is a quieter pause after the fortress, with plenty of places to sit and photograph the old warehouses around the water. For dinner, stay at The Dickens Inn, a timber-framed pub beside the docks, and allow £20–£35 per person for a main meal and drink. Check its Christmas opening hours and reserve ahead if possible, particularly for the holiday period; after dinner, it is an easy 15–20-minute walk back to St Christopher’s Inn London Bridge – The Village, or you can use Tower Hill and London Bridge on the District/Jubilee lines.
Start at Westminster Abbey, ideally for the first available visitor entry. Allow about two hours for the coronation church, Poet’s Corner and royal tombs; Christmas-period opening is especially variable, and services can restrict sightseeing, so book an official timed ticket and check the day’s access notices before leaving. From London Bridge, take the Jubilee line to Westminster—roughly 15–20 minutes including the walk and station transfer. Afterward, spend around 45 minutes around the Houses of Parliament and Big Ben from Parliament Square and the riverside; interior visits require a separate booking, so treat this as an exterior stop unless you have a confirmed tour.
Walk through St James’s Park toward Buckingham Palace, taking about an hour at an easy pace. The lake, bridge and waterfowl make this much nicer than simply following the main road, though winter daylight is limited and the paths can be damp. Continue via The Mall and Piccadilly to Fortnum & Mason, where the festive food halls are excellent for browsing and picking up edible souvenirs. Allow about an hour; opening hours and crowd controls may differ during the Christmas period, and the store is busiest in the afternoon. If you need a quick break, use one of the cafés inside rather than adding another cross-town detour.
Make your way to Dishoom Covent Garden for dinner, either walking through Soho in about 15–20 minutes or taking the Piccadilly line from Piccadilly Circus to Covent Garden. Budget £20–35 per person before drinks; the restaurant is popular, and walk-in waits can be substantial, so arrive before the main dinner rush or join the queue early. Afterwards, wander around Covent Garden and Seven Dials while the Christmas lights are on, then return to London Bridge by Northern line from Leicester Square or by bus; allow roughly 25–35 minutes door-to-door.
Start at British Museum in Bloomsbury, aiming for your reserved free timed entry soon after opening. Allow around 2½ hours for highlights such as the Egyptian galleries, Rosetta Stone and Parthenon sculptures; the museum is free, but special exhibitions cost extra, and festive opening hours or entry procedures can change. From London Bridge, take the Northern line north to Goodge Street or Tottenham Court Road, allowing roughly 25–35 minutes door to door. Keep your morning focused rather than trying to see every gallery—the museum is enormous, and a short coffee stop in Bloomsbury is worthwhile afterward.
Walk or take a short bus ride towards Seven Dials Market in Covent Garden for lunch. Its stalls make it easy for everyone to choose something different; allow about 1½ hours and budget £12–25 per person. Then spend an hour around Covent Garden Market, where the Christmas decorations, street performers and small independent shops create a lively festive atmosphere. It is busiest around lunchtime, so browse the covered market and surrounding lanes at an unhurried pace, keeping valuables secure in the crowds.
Continue on foot along the Strand to Somerset House, roughly 10–15 minutes away. Allow about an hour for the courtyard and seasonal installations; the ice rink or any ticketed Christmas event requires separate advance booking and should not be assumed available on the day. For dinner, walk back into Covent Garden to Rules, London’s historic restaurant. Reserve well ahead—especially during the Christmas season—and expect roughly £35–60 per person before drinks. After dinner, Covent Garden and the Strand are well lit for a final stroll; return to London Bridge by tube from Covent Garden or Charing Cross, usually taking around 20–30 minutes.
Start at Natural History Museum in South Kensington, ideally for a reserved timed entry soon after opening. Allow about 2½ hours for the Hintze Hall, dinosaur galleries and the building’s spectacular Victorian architecture. General admission is free, but festive opening hours and timed-entry requirements can change, so check the museum’s official site before travelling; queues are common during the Christmas period. From London Bridge, take the Jubilee line to Green Park, change to the Piccadilly line for South Kensington, and allow roughly 35–45 minutes door to door.
Walk a few minutes along Exhibition Road to the Victoria and Albert Museum for around two hours among its decorative arts, fashion, design and sculpture collections. Entry to the permanent galleries is generally free, though special exhibitions require tickets; reserve in advance if there is a particular exhibition you want. The museum is large, so choose a few galleries rather than trying to cover everything. For lunch, use the museum café or pick up something casual around Gloucester Road before continuing towards Knightsbridge.
Head to Harrods in Knightsbridge, about a 10-minute walk from the museums, and spend roughly 1½ hours browsing the grand interiors, Christmas displays and food halls. It is free to enter, but expect busy aisles and queues at the food counters during the festive season; keep bags manageable and allow extra time if you plan to buy gifts. In the evening, take the Piccadilly line from Knightsbridge to Earl’s Court, then walk about 15 minutes to The Churchill Arms in Kensington for dinner. This famously flower-covered pub is especially atmospheric at Christmas; budget around £20–35, and reserve a table if possible, as it fills quickly. Check its holiday hours and kitchen schedule before setting out, particularly if this day falls on a bank holiday.
Take your booked flight from London to Dublin Airport, allowing roughly 4–5 hours door-to-door once you include getting to the correct London airport, the airline’s check-in and baggage rules, security, the flight, baggage collection and the transfer into town. Follow the airline’s stated airport-arrival requirement rather than relying on the short airborne time. From Dublin Airport, the airport bus is usually the best-value option into the centre; allow approximately 35–60 minutes depending on traffic, then walk or take a short taxi ride to Abbey Court Hostel near O’Connell Street. Leave your bags at reception if the room is not ready, and keep the afternoon deliberately light after the travel morning.
After settling in, walk south across the River Liffey towards Trinity College Dublin and College Green. Reserve a timed ticket for the Book of Kells in advance, particularly during the Christmas period; allow about 1½ hours for the exhibition, the Long Room and the historic campus atmosphere. Festive opening hours and last admission can change, so check the official visitor information before leaving the hostel. For a quick coffee or snack nearby, Bewley’s Grafton Street is a dependable Dublin institution, though queues are common; otherwise, simply enjoy the streets around Grafton Street without adding another fixed attraction.
From Trinity College, it is an easy 10-minute walk through College Green and Dame Street to Temple Bar. Spend about an hour wandering its cobbled lanes and festively decorated streets, but treat it as a quick introduction rather than a full pub crawl: prices are higher here and the area becomes very crowded in the evening. Finish at The Old Storehouse for dinner, where a main course and drink will usually come to around €20–35. It is lively and atmospheric, so arriving slightly early is sensible; check whether Christmas-period service is operating normally and expect possible waits. After dinner, Abbey Court Hostel is roughly a 10–15-minute walk away, making an early night worthwhile after the flight.
Begin at Dublin Castle on Dame Street, ideally for the first available tour. Allow about 1½ hours for the State Apartments and medieval undercroft; holiday hours and tour availability can change, so check the official calendar and reserve if timed admission is offered. From Abbey Court, walk south across the Ha’penny Bridge and through Temple Bar—roughly 20 minutes—or take the Luas to Jervis and walk. Afterward, stay within the castle complex for Chester Beatty, whose beautifully presented Asian, Middle Eastern and European collections make it one of Dublin’s best small museums. Admission is generally free, with a donation welcome; allow another 1½ hours and leave time for the rooftop garden if open.
Walk about 10 minutes through The Liberties to St Patrick’s Cathedral, allowing an hour for the nave, memorials and Jonathan Swift’s connection to the cathedral. Confirm visitor hours before setting out, as Christmas services may restrict sightseeing; respectful dress is expected and entry is usually around €10–€12. Continue next door to Marsh’s Library, where the preserved 18th-century reading room and chained books are a compact but atmospheric visit of about 45 minutes. Its festive opening pattern can be limited, so treat this as the day’s most important availability check and have a relaxed wander around St Patrick’s Close if it is shut. Finish with dinner at The Brazen Head, a short walk away, budgeting approximately €20–€35 for a main meal; booking is sensible during the Christmas period, and the pub’s traditional rooms are more enjoyable than arriving at peak time.
Take the DART from Connolly Station or Tara Street Station to Howth; the journey takes about 30 minutes each way, with trains generally running several times an hour. Allow roughly four hours door-to-door for the coastal outing, including the walk, transport and a little time for viewpoints. From Howth Station, follow signs towards the harbour and cliff-walk routes. Choose the shorter or longer loop according to the weather and daylight—winter paths can be muddy and exposed, so wear proper shoes and bring a waterproof layer. The views over Dublin Bay are excellent, but do not approach the cliff edge in strong wind or poor visibility.
After returning from the cliffs, wander around Howth Harbour, where fishing boats, seabirds and small seafood stalls give the village its best atmosphere. Have lunch at Beshoff Bros, a straightforward local favourite for fish and chips; expect approximately €12–22, depending on your choice and portion size. It is casual rather than leisurely, so this works well after the hike. Check the day’s closing time before leaving Dublin, particularly around the Christmas period, when transport and restaurant hours may be reduced. Return to the centre by DART and allow about 30–40 minutes from Howth, plus time to walk back to the hostel.
Back in central Dublin, stop at the Molly Malone Statue on Suffolk Street for a quick photograph and a look around the surrounding lanes near Grafton Street; 20 minutes is enough. Continue on foot towards The Long Hall on South Great George’s Street, roughly 10 minutes away. Settle in for a classic Victorian Dublin pub interior and a quiet drink after the coastal day; budget around €8–18 for drinks or a light bite. Keep the evening unhurried, since the next day involves airport travel—check your flight’s terminal and baggage rules tonight, and confirm the first practical route to Dublin Airport before going to bed.
Start with the National Gallery of Ireland on Merrion Square, allowing about 1½ hours for a relaxed final look at its Irish and European collection. Confirm the Christmas-period opening hours and any special entry arrangements before leaving—holiday schedules can be shorter, and some galleries may close selectively. From Abbey Court Hostel, walk south through the city centre in roughly 20–25 minutes, or take a short taxi if you have luggage or the weather is poor. The gallery is free for the permanent collection; paid exhibitions, if available, are separate.
Walk west towards Grafton Street, taking around 15 minutes via Nassau Street and College Green. Spend about an hour browsing the shops and enjoying the seasonal atmosphere, but remember that Christmas trading hours and crowd levels vary. For your final Irish café stop, settle into Bewley’s Grafton Street—the historic interior is part of the experience. Allow roughly an hour and budget €10–20 for breakfast or lunch; queues are possible, so keep this flexible rather than booking a tight airport transfer around it.
Return to Abbey Court Hostel to collect your bags, ideally leaving the hostel about three hours before your flight. Dublin Airport is usually 25–45 minutes away by taxi or airport bus in light traffic, but allow extra time for city-centre congestion and the airport queue. The Airlink-style express buses and regular Dublin Bus services are cheaper, while a taxi is more convenient with luggage; confirm your terminal and airline’s baggage/check-in deadline in advance. At the airport, allow time for bag drop, security and possible Christmas queues before your flight to Mumbai.
